Sniffing out signs of life

...energy balance, forcing changes to its climate. VOCs clearly have an intimate relationship with Earth and its life. If we can develop ways to identify VOCs and where they might have come from, we can apply this knowledge to similar environments elsewhere, perhaps even to other planetary bodies where life might have existed in the past. The presence or distribution of VOCs...

The ageing brain: 'use it or lose it'

...energy consuming process. Food processing isn’t the only thing affected by ageing though. The way our bodies process medication slows down remarkably too with increasing age. This is mostly because our kidney and liver functions slow down naturally with ageing and we are often lightly, if not moderately, dehydrated. This means that any medication we take, takes longer...

Why is discovering gravitational waves from a neutron star collision a big deal?

...energy in a fraction of a second than the sun will pump out in ten billion years. For several decades we have observed these gamma ray bursts, but without knowing for sure what causes them. However, just 1.7 seconds after the gravitational waves from GW170817 arrived at the Earth, NASA’s Fermi satellite observed a short burst of gamma rays in the same general region of...

...energy to avoid climate change, and the Lukewarmers are saying, ‘Well, maybe we don’t need to avoid that much of it. Maybe in fact some degree of warming will be beneficial for us, it’ll encourage the growth of plants, for instance, with the extra CO2.’ TE: It’s interesting. A lot of what we aim to do with climate change of course comes down to our values. Do we...
